The gamma-camera is the most widely used imaging piece of equipment in nuclear medicine. The performance parameters of a routine gamma-camera quality control (QC) program include all of the following EXCEPT:

The dose calibrator’s ability to measure accurately a range of low-activity doses to high-activity doses is called:

As a result of a medical error, a dose of 0.25 Gy is delivered to the fetus during the early part of the first trimester of the pregnancy. Which of the following is the most likely clinical adverse outcome?

Spatial resolution and spatial linearity of a gamma-camera is assessed with a 4-quadrant bar phantom which consists of four sectors of lead bars and intervening plastic strips:

When tested Tc-99m sulfur colloid kit with TLC for free Tc-99m, the technologist noted: strip with free Tc-99m migrated to the solvent front reads 650 cpm, and strip containing Tc-99m sulfur colloid remaining at the point of origin reads 18350 cpm. What is the radiopharmaceutical impurity of this sulfur colloid kit?

When performing daily intrinsic floods, a point source of Tc-99m is placed five crystal dimensions away and centered over the detector. A point source should produce a measured counting rate not greater than:

650 Microcuries (uCi) is equal to?

Leak testing on sealed sources, e.g., dose calibrator standards, spot markers, etc. must be performed at intervals not to exceed:
